BDG-024-V/1-4-0

pluggable module, coupling impedance (R – resistance)

• lightning current arrester with coarse and fine surge protection for two 2-core signalling lines
• installation at the boundary of LPZ 0 and LPZ 1 zones or higher, at the line entry into building and also installation close to protected device
• for protection of communication interfaces of I&C, MaR systems, electronic security and fire detection systems, etc. (mainly for RS-485 inter- faces) against impact of surge voltage
• coarse and fine surge protection (core – core) in differential mode and coarse surge protection in common mode (line – PE)
